CHOCOLATE-rDEPOSITING MACHINE.

To all whom it may concern Be it known that I, Gnonon SA UEL BAKER, a subject of the King ofEngland, residing at Willesden Junction, London,

'N.vV., in England, have invented certain new and useful Improvements in Chocolate-DepositingMachines, of which the following is a specification.

This invent-ion relates to machines for depositing chocolate and other plastic substances into receptacles such as tins or molds, and relates more particularly to novel: forms of mechanism for transferring the filled tins or molds carried by wooden or other trays from the filling table of the depositing machine onto tapping tables e ther of single, double or multiple formation disposed adjacent to said filling machine.

The invention also relates to means for operating the transfer mechanism at the proper time or in proper sequence from said depositing machine. 1

The invention further relates to means for conveying the filled molds through devices for cooling the contents thereof, and for drying and returning the empty molds to a position near the depositing machine.

Embodiments of the invention are represented in the accompanying drawings in whichi Figure 1 is a diagrammatic elevation view showing the general arrangement of the machine. Fig. Qis a plan view of Fig. 1 with certain parts removed, showing two series of parallel tapping tables. Fig. 3 is a side elevation of the depositing machine proper, with certain parts omitted for clearness of illustration. Fig. 3 is an end elevation from the left hand. side of Fig. 3 with parts removed. Fig.4 is a side elevation with parts broken away of the filling table of the depositing machine, showing the mechanism for driving the tray feeding conveyer and the connection of said driving mechanism with a single transfer mechanism; Fig. 5 is a plan view of Fig. 4; Fig. 6 is a section taken on the plane of the line .66 of Fig. 5; Fig. 7 is a side elevation showing mechanism for actuating the driving mechanism shown in Figs. ito 6 from the main shaft of the depositing machine;

Fig. Sis a plan view ofFig: 7; Figs. 9, 10 and 11 are respectively a side elevation (partly in section on line 9-9 Fig. 10), plan view and end elevation of a double transfer mechanism for conveying the trays .alter- Speeification of Letters Patent.

nately to two different series of tapping tables disposed alongside one another as represented in Fig. 2; Fig. 12 1s a plan view showing a portion of the filling tableof the depositing machine and a portion of a single tapping table with the means for driving the conveyor chains of the tapping table and the means for actuating the tapping tables. Figs. 13 and let are respectively a side elevation and plan view of alternative mechanismto that shownin Figs; 7 and 8.

Referring to Figs. 1 and 2 the general arrangement and function. of the machine as a whole are as follows, it beingunderstood that either a siugleseries of tapping tables may be used in lieu of the two series shown in Fig. 2 or more than two such series if rc- Patented N ov. 2st, 1914:.

quired, the transfer mechanism being moditied or multipliedaccordingly. The depositing machine has theifeedhopper 1 and table 2 in which works the feed chain 3 for the trays and across which travel the primary transfer chains 4.

5 indicates the intermediate table used only when there are two .or more series of tapping tables and across which travel the transfer chains (5, saidtable having a raised inclined edge 7,.fora purpose hereinafter explained, and 8 and 9 indicate the two series of parallel tapping tables disposed at right angles to the depositingmachine 011 which the trays are shaken or jogged to com: pact the chocolate in the molds. Each of said series of tables is traversed longitudinally by pair of conveyor chains 10 and 11 respectively and the alternate transfer At the end of the tappingtable or tables the trays of filled molds pass under a roller 13 provided with dies such as 1 t for impress ing a mark on each deposit for identifying each batch of material treated. On reaching the ends of the tables the filled molds are removed from the trays by hand and placed on an endless conveyor or conveyers 15 (two being shown in Fig. 2) which traverse a cooling chamber 16 of considerable length preferably contained in a separate room divided from the room in which the tapping tables are situated by an insulating partition, the trays themselves being returned by hand to the depositing machine for receiving a fresh supply of empty molds. lhe cooling chamber may be of any appropriate construction, that shown in the drawings includin a coolin coil 1.? and a fan 18 upon still higher conveyers 20 which pass them to inclined belts 150 traversing narrow apertures in the partition referred to and deposit them upon other conveyers 151 traversing drying chambers 21 suspended from the ceiling and conveying said molds to piling boxes or chutes located at points adjacent the depositing machine. The con veyers may be driven shown from step pulleys 152 located at the sides of the machine through worm and worm wheel gear and spur gear and the conveyers 19 and may be driven from the pulley shaft 190 by chain transmission 191, 19:2 respectively or other means may be used.

Referring now to Figs. 3 and 3 this shows a depositing or mold filling machine of known construction having the table 2 traversed by the chain 3 carried by chain pulleys 301 and 302 and provided with abutments for engaging the edges of the trays filled with the molds and placed on the table. The chain pulley 301 is mounted on a shaft hereinafter referred to. Above the table is the feed hopper 1 provided with the feed rolls 23 geared together and operated from the main shaft by eccentric 25, rodQG ratchet and pawl mechanism 27 and gear 28. The material is dischar ed from the hopper by the pump 29 operated from the shaft by the eccentric 30 and rods 31 and 32 (between which is interposed a link for adjusting the stroke of the pump) the material being discharged by said pump through a slide (not shown) positively operated in both directions from the main shaft 241: by means of two cams 35, levers 3G, lever 3"? and rod 38.

The table 2 is of the known rising and falling kind, beingv pivoted at its or left hand end. movement being imparted thereto from the main shaft 2% by the cam 39, bell crank lever 10 and rod 41, the ebb tent of movement being regulated by the nut .42 and rod ll, the left hand end of the table rocking upon its pivotal point. The required intermittent feed movements of the chain 3 are produced by pawl and ratchet mechanisms shown in Figs. 3 and 3 One of such mechanisms moves the chain at the desired uniform rate while the chocolate is being deposited to fill the molds and then stops said chain, this mechanism comprising a finely toothed disk 80 mounted on the shaft and a pawl l? carried by an arm 47 operated from the main shaft 2 f by means of a cam 48 thereon, lever l8 and rod as. Also mounted on the shaft at the opposite side of the machine is another finely toothed disk operated by'a pawl 42 carried by an arm 4C2 operated by means of a cam 4% on shaft 2 1:, lever l land rod 15. This second ratchet and pawl mechanism feeds'the chain 3 when no chocolate is being deposited, that is to say, its pawl carrying arm 42 moves forward when the corresponding arm -17 of the first mentioned mechanism is moving rearward and thus feeds the chain 3 to bring further molds into position for a fresh deposit.

Referring to Figs. 4;, 5 and 6, it will be seen that below the table is a shaft 50 adapted to be rotated at the required times by means hereinafter described through the bevel gears 51, 52 the latter being loosely carried by a shaft on which is mounted the chain pulley S01 and the chain feed mechanisms previously described. The opposite end of the shaft 50 carries a pair of chain wheels 5 f about which pass the two transfer chains l, 1 (see also Fig. 2), passing also around other upper pulleys 5&0 and traversing slots 55 in the table and provided with projections in the known manner. These chains engage the tray fed along by chain 3 and transfer them in succession either to the intermediate table (Fig. 2) where two or more series of tapping tables are employed or direct to the tapping tables where there is only one series thereof. A third transfer chain 101 (Figs. 2 and 10) nearer the feed hopper and arranged similarly to those just described may be employed if required, such third chain being found desirable in cases where the trays are not sufliciently long to be fed far enough to be properly engaged by the outer pair of chains 4, 4%. The transfer chains i and 4:01 are driven at a faster speed thanthe feed chain 3 for example at twice the speed so as to effect the transfer quickly and afford the desired spacing of the trays on the tapping tables.

For assistance in carrying the trays to the end of the table so that the transfer may be I neatly and efficiently effected by the chains 4, l, 1 may provide in the table a slot 56 through which slightly extends the roughened surface of a roller 57 driven in the direction of the arrow, Fig. 4:, at a faster speed than the chain 4, for example, at

twice the speed by means of a bevel gear 58 on shaft 50 meshing with bevel gear 59 on shaft 60 carrying a spur wheel 61 meshing with pinion 62 on the shaft of said roller, the latter engaging the under surface of the tray and carrying it rapidly along toward the outer end of the table without relying on the pushing actionof the succeeding tray to complete the movement when the first tray has left the chain 3. Those trays which commence to be transferred from the table 2 at points nearer the feed hopper l engage the inclined abutment 7 (Figs. 2 and 10) which guides them in a diagonal or inclined course across the table 5 either to the tap ping tables 8 or to be acted on by the transfer chain 12 for conveyance to the tables 9. Two forms of mechanism employed for operating the shaft 50 at the required times from the main driving shaft 2 1 of the depositing machine are shown in Figs. 7 and 8 and 13 and 11 respectively. Referring to Figs? and 8, such mechanism comprises a lateral projection on the disk before referred to or on a disk 81 or equivalent moving therewith on the shaft 53, said projection acting on roller 82 mounted on arm 83 integral with an inclined rock shaft 8-1 the opposite end of which carries a forked clutch member 85 embracing the main shaft 21. One arm of said member 85 is provided a with a roller 86 and the other arm bears against a disk 87 slidably mounted on the shaft 21 and carrying a pin 88 adapted to engage an aperture 89 ina chain wheel 90 loosely mounted on shaft 24. The said wheel 90, is connected by chain 91 to another chain wheel 92 in rigid connection with the bevel gear 52 before referredto loose on the shaft 53. It will thus be seen that when the projection 70 engages the roller 82 and rocks the arm 83 and consequently the shaft 81 the engagement of said pin 88 and aperture 89 will be effected and thus cause the chain wheel 90 to take part in the rotary moveagainst a disk 92 rotatable with wheel 90 and having an enlarged flange portion 93 which, when it comes into contact with said roller forces back the clutch 85 and releases the chain wheel 90 thus stopping the movement of the chains 4, etc. The alternative mechanism shown in Figs. 13 and 14: and the operation thereof is as follows :To the shaft 2 1 is keyed a chain wheel 133 which drives the intermeshing gear wheels 134- and 135 through the medium of chain 136, chain wheel 137 and spindle 138. On the shaft 139 of gear wheel 135,is fixed a disk wheel 140 to which is attached a cam roller 141.

'fit the periphery of disk wheel 1 10. It will be evident that during a part revolution of the disk wheel 140, the star-wheel 1411 is caused to revolve through a definite angle by means of the cam roller 1&1 engaging a slot, while duringthe remainder of the revolution the wheel 1 11 is locked by the periphery of said wheel engaging a concave surface of the star-wheel, until the cam roller 1411 engages another slot 144: whereupon the star-wheel will be rotated through another definiteangle until the roller leaves the slot whereupon it is again looked as described, this intermittent motion being transmitted to shaft 50 by means of the bevel wheel 141-2 and pinion 1 13, and thence to the transfer chains 4:, etc., as previously mentioned. It will be seen that the shaft 50 will onlyrevolve after the shaft 21 has made a definite number of revolutions, at other times remaining stationary and the number of revolutions which will intervene between the movements of shaft 50 can be altered by replacingigear wheels 131 and 135 by others of different diameters.

Referring to Figs. 9, 10 and 11, which Fig. 2) arranged over the intermediate table 5 and having a downwardly extending lug or abutment 200 to engage the edge of a tray at position I (Fig. 10) and carry same rapidly to position II, where it is engaged by the chains 11 of the second series of tapping tables 9. lhe chain 12 and the different transfer and conveyor chains con cerned in'this form of device may be driven by various meims but those shown in the drawings include a chain wheel continuously drivenfrom the shaft 2 1 of the depositing machine and driving through bevel gears 101, 102, a shaft 103 carrying chain Wheels 104 over which pass the cone veyer chains 11. of the tables 9, and also other chain wheels over which pass the conveyor chains 10 of the tables 8, these chains passing over suitable guide pulleys 100. The other transfer chains 6, (i, traversing the table 5 are also driven from shaft 103 at an increased speed relatively to that of the chains 10 and 11 by passing around chain wheels 107 on shaft 103 of larger diameter than the chain wheels 10 1 and 105. The said chains 6 are guided at the level of table 5 by means of pulleys 108. The bevel gear 102 before referred to, also meshes with another bevel gear 108 on shaft 109 from which is driven at twice the speed of the shaft 103 a chain 110 adapted to drive the half-time interrupted gears 111, 11.2,the latter being on a shaft 113 carrying a chain wheel 11 1- connected by chain 115 to chain wheel 116 on shaft 117 above the table, said latter shaft driving through chain 118 a shaft 119 from which the chain 12 is driven. lhus for every complete revolution of the chain wheel 100 the chain 12 is actuated during half of such revolution by gearing 111, 112 and parts described and remains at rest during the remainder of such revolution, whereby every other tray when at position 1, Fig. 10, has its left hand end en' gaged by abutment 200 on the chain 12 and is carried by the latter to-position 11, Fig. 10, where it is engaged by the chains 11 and conveyed to the series of tables'9 where they are engaged by said chains 11.

Fig. 12 shows means for driving the conveyer chains 10 of the tapping tables where a single series thereof is used, such means comprising a chain wheel 120 actuated in a similar manner to wheel 100 and driving through bevel gears 121, 122, a shaft 123 carrying chain wheels 12% about which said chains pass and are guided by pulleys 125. This figure also shows independently driven means for operating the tapping elements of the tables comprising the pulley shaft 126 driving through bevel gears 127, 128 a longitudinal shaft 129 on which the tapping cams are mounted in the known manner. The tapping mechanism may, however, also be driven from the same source as the de positing machine as shown in Fig. 2, where 130, 131 denote belts driving said tapping means and machine respectively and 132 bevel gearing driven by belt 130 and operating the tapping mechanism.
